Re: 09 ds won't keep speed
So I did the motor test and I have continuity on f1 and a1 which shouldn't have continuity..... so that means the brushes need to be replaced?? ((I tried it on a fleet ezgo motor))
I will be doing the same test on the club car ds I'm having trouble with soon |

Brushes would be an assumption, could be as more as M70 stated. Best to pull it and have it inspected. |

Re: 09 ds won't keep speed
Motor seems fine.... cleaned it but the armature had grooves in it where the brushes go around and it starts off fast then dies to 13mph

Re: 09 ds won't keep speed
Your speed sensor signals were never correct, since you have tried so many, you either have a bad controller or something wrong in the harness between the sensor and the controller.
The most telling problem was the inability of the speed sensor to bring the Green wire to 0v, since the hall effect sensor simply brings that output to negative, it should have gone down to 0v if the sensor was working. Make sure the Black/White and the Red wires match with the corresponding colors on the 3-pin speed sensor connector (in case someone messed with the harness). You should also try using piercing probes to measure the Red wire to Black/White wire on the Sensor 3-pin connector (connector in place) while turning the wheel to make sure the voltage stays at around 15v. If that voltage changes, check the continuity/resistance between: Black/White wire to Controller pin #13 |
